In Article 3 and Article 16
of the Convention on the Protection of the Marine Environment of the Baltic Sea
Area, 1992 (Helsinki Convention), the Contracting Parties agreed to undertake
measures to prevent and eliminate pollution of the marine environment of the
Baltic and to provide pollution load data, as far as available. Compilations of
pollution load data (PLC) have been an integral part of HELCOM assessment
system since 1987, focusing on annual and periodic assessments of inputs of
nutrients and selected hazardous substances.

based on annual water- and airborne data on nitrogen, phosphorus and selected
heavy metals from 1995-2017, periodical data from 2017 supplied with periodical data
reported in 2006 and 2014.

The project results will include such products as: an update of the pressure indicator report
on progress towards fulfilment of Maximum Allowable Inputs of nutrients (MAI); an assessment of progress towards implementation of Country Allocated
Reduction Targets (CART);thematic reports on sources of nutrients, effectiveness of measures to reduce nutrients inputs to the Baltic Sea and input of hazardous substances.
